Getting this urine-like smell is essential to keep your laundry smelling fresh and to ensure an amazing laundry experience.
The causes of this pet urine-like smell and how to get rid of them will be explained in detail in this article.

Why does my dryer smell like pee?
Your dryer smelling like pee or having a horrible smell could be due to several reasons, these reasons are explained below.
Pets
These are the primary culprits in this situation, if you probably have a pet if your dryer smells, and you are facing this issue. The presence of pets like cats in your home can lead to various issues related to your dryer’s odor, these issues typically result from pet hair, dander, and occasional accidents leading to the smell of cat urine.

Cats and many pets shed fur and dander regularly.
When this hair and dander come into contact with your laundry and are subsequently dried in the dryer, they can create a buildup of allergens and unpleasant odor, ultimately leading to your laundry smelling like pee.
Your dryer smelling like cat pee can also be because of pet dander and allergenic residues left on clothing can be transferred to the dryer’s interior, when subjected to heat, these residues can emit a cat pee-like or unpleasant odor.
Residues of cat urine left on clothing or bedding can emit a strong, cat pee odor when exposed to the heat of the dryer, causing your laundry to smell like cat pee.

Cat hair and lint can accumulate in the lint trap and exhaust ducts of your dryer, creating an environment conducive to bacterial and mold growth, leading to the smell of cat pee or an unpleasant odor.
Dirt and mold growth
When wet clothes are dried, the environment of a dryer may get moist, this dampness has the potential to turn into a favorable environment for mold and mildew over time.
The lint trap and ducts frequently become clogged with lint, and the minute fibers that fall off your clothing as it dries may facilitate the growth of mold when combined with moisture.
Clothing containing stains from urine or soil might occasionally end up in the dryer. When heated, these impurities may emit scents that stick to the dryer’s interior, and fungi like mold and mildew flourish in wet, dark, and poorly ventilated areas. For the reasons listed above, your dryer may provide these favorable conditions for mold growth.

Even after the drying cycle is finished, moisture could still be present in the drum or lint trap, particularly if you use your dryer frequently at low temperatures.
Ventilation issues
Ventilation issues in a dryer refer to problems with the proper flow of air and moisture during the drying process, the dryer’s inability to effectively discharge moist air can lead to several issues, including the formation of bad odor.
The main purpose of a dryer is to dry wet laundry by removing moisture, the dryer, lint trap, and venting system may become congested with damp air if it is not properly vented outside.
Mold, mildew, and bacteria thrive in the trapped moisture, which can result in stinky or unpleasant scents.
The lint trap, exhaust ducts, and venting system can become clogged with lint, microscopic threads, and particles that fall off your clothing as it dries. Lint and dampness can create an unpleasant smell that seeps into your laundry when they combine with moisture.
The dryer may overheat when ventilation is blocked, this high heat can cause lint and debris to burn, emitting a strong burnt odor, The lint trap is designed to catch lint and a dirty lint trap can drastically reduce airflow.
Wet environment
The environment in which your dryer operates has a big impact on how well it works and may influence how it smells.
A wet environment can lead to several issues, including the formation of mold and mildew, which can cause odors to come from your dryer.
In humid, dark, and poorly ventilated areas, mold and mildew flourish, these fungi thrive in constantly damp environments, like your laundry room or the vicinity of your dryer. Once they take hold, they can release musty and unpleasant odors into the air.

Damp conditions can exacerbate the problem of lint accumulation within your dryer, lint absorbs moisture and can develop unpleasant smells, which can then be transferred to your clothing during the drying process.
Ventilation may be compromised in a moist atmosphere, When the dryer’s exhaust system fails to vent damp air outside successfully, moisture may build up inside the dryer and its ducts, which might result in your clothes smelling like cat pee.

A moist atmosphere harms your dryer if there is a continuous musty or moldy smell, especially on your dried laundry.
Cleaning products
Cleaning supplies like detergents, fabric softeners, and stain removers are essential for keeping your clothes clean and smelling fresh, however, when these chemicals are used improperly or mixed with other products, they might cause odors inside your dryer.
Even after a thorough washing, certain cleaning products contain substances that can leave a residue on your clothing, these residues may react and release foul odors when they come into touch with the dryer’s heated surfaces during the drying cycle.

Combining different cleaning products with incompatible chemicals, such as bleach and ammonia-based detergents, can result in chemical reactions that, when heated, produce potent and offensive aromas.
How do I get rid of the cat urine odor?
There are several ways to rid your dryer of cat pee smell or any unpleasant smell, these ways are explained below.
Proper ventilation
Ventilation is the process of circulating and exchanging the air in an area to get rid of impurities, odor, and moisture.

The removal of moisture from the clothes is one of the dryer’s main goals. By ensuring that moist air is removed from the dryer and replaced with dry air, effective ventilation prevents the accumulation of moisture that can cause odors, giving your laundry room a urine-like smell and making your laundry smell like cat pee.
Odors are more easily dispersed and are less likely to remain inside the dryer with enough ventilation, this is important when handling cat urine scents, which are usually strong.
Ensure that your dryer’s exhaust duct is correctly installed and free from obstructions. A clogged exhaust vent or a clogged dryer vent prevents the efficient expulsion of moist air to easily circulate fresh air. A clogged dryer vent also prevents an efficient experience while doing laundry.
Consider installing an exhaust fan in your laundry room to enhance air circulation and keep your dryer smelling fresh, this is particularly beneficial if your laundry area lacks natural ventilation through windows or vents.
Using baking soda and vinegar
Baking soda, also known as sodium bicarbonate, is well known for its ability to mask odors, it works by absorbing and neutralizing odors and is very handy if your laundry smells like cat pee.
White vinegar is also a versatile household cleaner that is well known for its capacity to degrade and eliminate odors, which makes it also handy if your clothes smell like cat pee.

Both vinegar and baking soda are two powerful and natural solutions for eliminating cat urine odor in your dryer, to use baking soda, start by carefully scattering it throughout the dryer drum, and make sure it is distributed evenly.
For best results, leave it for several hours or even overnight, this gives it plenty of time to absorb and eliminate the smell of cat urine.
After the waiting period, take the soda out of the dryer drum with a clean, damp cloth or a vacuum cleaner with a hose attachment.
To use vinegar, mix equal parts of vinegar and water in a spray bottle, for example, one cup of vinegar to one cup of water, spray the vinegar-water solution inside the dryer drum, focusing on areas affected by the cat urine odor and allow it to sit for around 18 minutes.

After the waiting period, use a clean cloth or sponge to wipe down the interior of the dryer, ensuring that you remove any residues of cat urine and the vinegar solution.
Rinse the dryer interior with plain water and wipe it dry with a clean cloth to remove any remaining traces of vinegar.
Hydrogen peroxide
Hydrogen peroxide is a versatile and gentle antiseptic and disinfectant that is typically accessible in most homes. Its ability to disintegrate and neutralize the chemicals responsible for the unpleasant smell is what makes it so efficient in getting rid of pet urine odor.
Mix equal volumes of water and hydrogen peroxide in a clean spray container and put on gloves to protect yourself from the solution getting on your skin.
Spray the hydrogen peroxide solution generously inside the dryer drum, concentrating on areas affected by the cat urine odor and ensuring that the solution is evenly distributed.
Allow the mixture to settle for about 25 minutes, the hydrogen peroxide will work to degrade and eliminate the odor-producing substances during this time.

Use a clean cloth or sponge to clean the interior of the dryer after the waiting period has passed, making sure to get rid of any remaining cat urine and hydrogen peroxide solution.
Enzymatic cleaner
Enzymatic cleaner is made specifically to degrade and get rid of organic stains and odors, including cat urine scents. Enzymes in these cleaners hunt down and break down the proteins and other substances that cause odors.
Choose an enzymatic cleaner designed for pet stains and odors and prepare the cleaner solution according to the manufacturer’s directions. Normally, you should dilute it with water, following the instructions on the product label.

Concentrate on the places where the cat urine smell is strongest, and spray the dryer drum with the enzymatic cleaner mixture.
As directed on the product label, let the enzymatic cleaning solution sit for the recommended amount of time, this enables the odor-producing chemicals to be broken down and digested by the enzymes.

Charcoal
Charcoal is an amazing and natural odor-absorbing substance, it’s known for its ability to trap and neutralize a wide range of odors. Find activated charcoal or charcoal odor absorbers designed for home use, open the container or bag of charcoal, and place it inside the dryer drum.

The amount of charcoal needed may vary depending on the product’s instructions and the severity of the odor.
Keep the charcoal inside while sealing the dryer door, for about 10 minutes, you can run the dryer on a quick, no-heat cycle to help distribute the charcoal and activate its odor-absorbing properties.
Allow the charcoal to sit inside the closed dryer for several hours or overnight, during this time, the charcoal will absorb and neutralize the cat urine odor.
Open the dryer door and carefully remove the charcoal, dispose of it according to the product’s instructions, and get rid of any remnants in the dryer.
